Burmistr O. Synthesis, properties and application of polyionenes based on epoxidized derivatives of 1,2-epoxy-4,7-dioxinonen-8.

The dissertation is devoted to the synthesis of polyionenes (PI) based on epoxidized derivatives of 1,2-epoxy-4,7-dioxinonen-8, to research of viscosimetric, physical-mechanical, thermal properties of these polymers and determination of possibility to apply new PI in different chemical-technological processes. It was established, that synthesized monomers have sufficient reactivity in PI formation reaction. However the molecular weight of PI depends on nature and composition of solvent. Studying peculiarities of PI synthesis reaction allowed to determine optimum conditions for these polymers synthesis. It is shown that synthesized PI have classical polyelectrolyte behavior in aqueous, organic and aqueous-organic solutions. It was determined that chemical structure doesn't influence on maximum position in concentration dependences of viscosity of PI aqueous solution. It was revealed anomalous behavior of synthesized PI in aqueous-alcoholic solution it means viscosity of aqueous-alcoholic solution is lower than solvent viscosity. It was determined, that PI based on epoxidized derivatives of 1,2-epoxy-4,7-dioxinonen-8 are thermally stable up to 83-2000С. PI Ionic conductance at room temperature is 10-2-10-3 См cм-1. It was established dependence of PI ionic conductance on their cationic part structure. PI based on epoxidized derivatives of 1,2-epoxy-4,7-dioxinonen-8 can be applied as component of liquid and polymeric electrolytes for new type different electrochemical devices. For the first time it was carried out structured research of synthesized PI influence on rheological properties of triacetate cellulose (TAC) solutions, thermodynamic characteristics of TAC solutions flow viscosity; physical-mechanical, dielectric, thermalphysical properties of films, obtained from TAC solutions. It was determined that synthesized PI are effective modifiers of TAC compositions. It was studied the bentonite coagulation kinetics at synthesized PI introduction. It was established that synthesized PI can be used as accelerators of sedimentation process and as stabilizers of bentonite clay suspension.
